A high-surf and rip-current warning has been issued for the Ventura County coast through Sunday afternoon, according to the National Weather Service.

Waves of 4 to 7 feet are likely to affect beaches, with some waves measuring up to 9 feet. The peak waves are expected Saturday morning and on south-facing beaches, according to forecasts. In addition to the tall waves, rip currents may be present throughout the weekend.

Beachgoers this weekend are urged to stay out of the water unless they're near a lifeguard station. Authorities also advise the public to stay off rocks and jetties, and to never turn their back to the ocean.

The high surf is caused by a south swell from Hurricane Sergio. The National Hurricane Center says Sergio is a Category 3 hurricane with maximum sustained winds of 120 mph. Depending on the direction of the storm, there may be high surf into next week, according to the National Weather Service.
